Whats the difference between PPM meters

OK so my Blulabs PH PPM Temp meter just shorted out. I spent about 200 bucks for this meter 2 years ago.

I was wondering what are the differences between these meters. Why did I spend 200 bucks for a meter that measures the same thing as a 76 dollar meter on ebay.

I can spend the money again, but is it worth it?

well you'll need a meter. the difference is accuracy. the $200 meters are generally more accurate than the $76 ones. but the cheaper one will still work.

because the one you have reads faster more accurate and have auto temperature compensation. My hanna meter which reads ph/tds/temp and has a unique feature called cal check make sure my meter is well calibrated accurately, plus its water proof.

I just ordered a set of 2(ph2 and ppm2.5) off ebay. They were the best price I could find with the level of accuracy I wanted. They only cost me 85 for both, and their made by control wizard.

So my Bluelab has a 5 year warranty, does anyone know how long it takes for them to turn it around? I think I'm gonna have to go get some cheapies in the mean time

Are the hanna primo "wands" ok for backup meters?

call your hydro store dude and tell them what happen they should replace it real quick, same thing as ordering a new meter anyway.

unfortunately, the shop where it was bought i in California. The closest Bluelab dealer is about a 3 hour drive from me.

So are the Hanna wands any good for a couple of weeks?
